Configuring 802.11 Bands
Note On access points that run Cisco IOS software, this feature is called world mode.
Note DTPC and 801.11h power constraint cannot be enabled simultaneously.
Step 7 Use the Data Rates options to specify the rates at which data can be transmitted between the access point
and the client. These data rates are available:
• 802.11a—6, 9, 12, 18, 24, 36, 48, and 54 Mbps
• 802.11b/g—1, 2, 5.5, 6, 9, 11, 12, 18, 24, 36, 48, or 54 Mbps
For each data rate, choose one of these options:
• Mandatory—Clients must support this data rate in order to associate to an access point on the
controller.
• Supported—Any associated clients that support this data rate may communicate with the access
point using that rate. However, the clients are not required to be able to use this rate in order to
associate.
• Disabled—The clients specify the data rates used for communication.

Using the CLI to Configure 802.11 Bands
To configure 802.11 bands using the controller CLI, follow these steps:
Step 1 Disable the 802.11a band by entering this command:
config 802.11a disable network
Note The 802.11a band must be disabled before you can configure the 802.11a network parameters in
this section.
Step 2 Disable the 802.11b/g band by entering this command:
config 802.11b disable network
Note The 802.11b band must be disabled before you can configure the 802.11b network parameters
in this section.
Step 3 Specify the rate at which the SSID is broadcast by the access point by entering this command:
config {802.11a | 802.11b} beaconperiod time_unit
where time_unit is the beacon interval in time units (TUs). One TU is 1024 microseconds. You can
configure the access point to send a beacon every 20 to 1000 milliseconds.
Step 4 Specify the size at which packets are fragmented by entering this command:
